what is -100x and what is x
Answer:
-100x=-100
x=1
Step-by-step explanation:
(simplifying the equation)
-100x-100=0
-100x=-100 they subtracted -100 from both sides
x=1 then divided by -100

f (x) =x^2-6x+4 how do i find the vertex ?
Answer:
(3, -5)
Step-by-step explanation:
So, there are three steps in finding the vertex.
We need to first find a, b and c. a is the x^2 coefficent, b is the x cofficent, and c is the number value. In this case:
a=1, b=-6, and c=4
To find the x value of the vertex, plug in a and b into the formula:
-b/2a = x coord of vertex:
-*-6/2*1
=
6/2
=
3
So the x coordinates of the vertex is 3.
To find the y cooridnates, plug in 3 into the orginal equation:
[tex](3^2)-(6*3)+4[/tex]
=
[tex]9-18+4[/tex]
=
[tex]-5[/tex]
So -5 is the y coordinates of the vertex.
Answer:
(3, -5)
Hope this helps!
Going over steps:
Step 1 - Find values a b and c: a=x^2 coefficent. b=x coefficent. c=number
Step 2 - Plug in a and b into -b/2a
Step 3 - Plug in x into equation
The sum of three numbers is 103. The second number is 5 less than the first. The third number is 4 times the first. What are the numbers?
Answer:
The numbers are 18, 13, and 72.
Step-by-step explanation:
Let the three numbers be represented by a, b, and c.
The sum of the three is 103. Thus, we can write that:
[tex]a+b+c=103[/tex]
The second number is five less than the first. So:
[tex]b=a-5[/tex]
And the third number is four times the first. So:
[tex]c=4a[/tex]
Substitute:
[tex]a+(a-5)+(4a)=103[/tex]
Solve for a. Combine like terms:
[tex]6a-5=103[/tex]
Add five to both sides:
[tex]6a=108[/tex]
And divide both sides by six. Therefore:
[tex]a=18[/tex]
So, the first number is 18.
Since the second number is five less than the first, the second number is 13.
And since the third number is four times the first, the third number is 72.

a= -0.12
Which system of equations could you use to determine where the paths intersect?
=B) y = 0.8x and y = -0.12x2 + 20
Step-by-step explanation:
your welcome <3
Based on the graph, the values of the constants in the vertex form of the quadratic equation are:
h = 0.k = 20.a = -0.12.How to write a function.Generally, the vertex form of a quadratic equation can be used to model or write an equation of the function of a graph.
Mathematically, the vertex form of a quadratic equation is given by this formula:
y = a(x - h)² + k
Where:
h and k represents the vertex of the graph.
Note: The sign on "a" indicates whether the quadratic equation opens up or opens down.
Based on the complete information, we can deduce that the values of the constants in the vertex form of the quadratic equation are:
h = 0.k = 20.a = -0.12.Read more on vertex here: brainly.com/question/525947

Tracey paid $374.25 for a new iPad. What was the original cost if the iPad was on sale for 25% off
Answer:
$467.8125
Step-by-step explanation:
Percentage increase = 25% × 374.25
New value = 374.25 + Percentage increase
New value =
374.25 + Percentage increase =
374.25 + (25% × 374.25) =
374.25 + 25% × 374.25 =
(1 + 25%) × 374.25 =
(100% + 25%) × 374.25 =
125% × 374.25 =
125 ÷ 100 × 374.25 =
125 × 374.25 ÷ 100 =
46,781.25 ÷ 100 =
467.8125 ≈
467.81

The width of a rectangle, in feet, is represented by (3x + 2). The length of the rectangle, in feet, is represented by (5x + 4). Find the perimeter of the rectangle
Answer:
2*(5x+4) + 2*(3x+2)
= 10x + 8 + 6x + 2
= 16x + 10
The perimeter of the rectangle, in feet, is represented by (16x + 10)
Answer:
(16x + 12) ft
Step-by-step explanation:
Perimeter of the rectangle = 5x + 4 + 3x + 2 + 5x + 4 + 3x + 2
Perimeter of the rectangle = (16x + 12) ft
Coffee is sold in two different-sized canisters. The smaller canister has a diameter of 9 cm and a height of 12 cm. The larger canister is double the size of the small canister. Calculate the volume and surface area of each canister and compare the results of doubling the dimensions.
Answer:
Step-by-step explanation:
Smaller Canister:
Height, h = 12cm
Diameter = 9cm
Radius, r = 4.5 cm
[tex]Volume = \pi r^2h\\[/tex]
[tex]=\pi \times 4.5^2 \times 12\\\\=243 \pi \ cm^3[/tex]
[tex]Surface \ area = 2 \pi r(r + h)\\[/tex]
[tex]=2 \times \pi \times 4.5 ( 4.5 + 12)\\\\= \pi \times 9(16.5)\\\\=148.5 \ cm^2[/tex]
Larger Canister:
Measures double the smaller canister, that is
height, H = 24 cm
Diameter = 18cm
Radius, R = 9cm
[tex]Volume = \pi R^2 H\\[/tex]
[tex]= \pi \times 9^2 \times 24\\\\= \pi \times 81 \times 24 \\\\= 1944 \pi[/tex]
[tex]Surface \ area = 2 \pi R(R+ H)[/tex]
[tex]= \pi \times 2 \times 9 ( 9 + 24) \\\\= \pi \times 18(33)\\\\=594 \pi \ cm^2[/tex]
Comparing results :
[tex]Volume_{small} = \pi r^2 h\\\\Volume_{large} = \pi R^2 H = \pi(2r)^2(2h) = \pi(4r^2)(2h)= 8 \pi r^2h = 8 \times volume_{small}[/tex]
Therefore, volume of larger canister is 8 times the volume of smaller canister.
[tex]Surface\ area _{larger} = 2 \pi R(R + H) = 2 \pi(2r)((2r+2h))\\\\[/tex]
[tex]=2 \ pi \times 2r \times 2 (r+ h)\\\\= 4 \times 2\pi r(r+ h) \\\\= 4 \times surface\ area_{smaller}[/tex]
Therefore, surface area of larger canister is 4 times the surface area of smaller canister.

A pizza delivery man makes $50.00 a shift. If he makes $3.00 on each delivery he makes, how much will he make if he makes 22 deliveries in one shift? Create an equation to represent this situation. Write the equation in function notation. State the ordered pair for 22 deliveries and explain your solution.
Answer:
f(x) = 3x + 50 is the equation in function notation.
(22, 116) is the ordered pair for 22 deliveries.
Step-by-step explanation:
First, create the equation. Let x represent how many deliveries he makes.
Since he makes $3 on each delivery, the total amount he makes from deliveries can be represented by 3x.
He also makes $50 a shift, so add this to 3x in the equation:
f(x) = 3x + 50 is the equation in function notation.
Find how much he will make if makes 22 deliveries. Plug in 22 as x:
f(x) = 3x + 50
f(22) = 3(22) + 50
f(22) = 66 + 50
f(22) = 116
So, he will make $116.
As an ordered pair, the solution is (22, 116).
Answer:
f(x) = 3x + 50
Step-by-step explanation:
If he makes $50.00 a shift, and $3.00 for each delivery, and he makes 22 deliveries in one shift then the equation (in function notation) would be f(x) = 3x + 50. and the solution to the equation is 116.
Paul purchases an antique circular frame for his mom for Mother's Day. The diameter of the frame is 18 cm. What is the area of the bowl
Answer:
254.34cm²
Step-by-step explanation:
the bowl is shaped is shaped in the form of a circle
Area of the bowl is equal to the area of a circle
area of a circle = πr²
π = 3.14
r = 18/2 = 9
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
3.14 x 9² = 254.34cm²
how do i find the area for number 4?
Explanation:
Form a horizontal line as shown below (see attached image). This forms 2 separate smaller rectangles
The bottom rectangle has area of 4*8 = 32 cm^2The top rectangle has area of 3*3 = 9 cm^2The total area is therefore 32+9 = 41 cm^2
You can say "square cm" or "sq cm" in place of the "cm^2".
You can solve this in two different ways. In both ways, however, use the formula for the area of a square/rectangle. The formula is:
Area = Length x Width
A = L x W
To solve, divide the shape given into two rectangles. Then, find the areas of the two different rectangles and add them

The sum of two numbers is 33 and thier difference is 2 find the number
Answer:
17.5 + 15.5
Step-by-step explanation:
17+ 15 = 32
.5 + .5 = 1
32 + 1 = 33
Answer:
15.5 and 17.5
Step-by-step explanation:
Let x and y be the two numbers
x+y = 33
x-y = 2
Add the two equations together
x+y = 33
x-y = 2
-----------------
2x = 35
Divide by 2
2x/2 = 35/2
x = 17.5
Substitute into
x+y = 33
17.5 +y = 33
y = 33-17.5
y = 15.5

Construct the 95% confidence interval estimate of the mean VAS score for patients given the magnet treatment. Find the Standard error and critical value. construct the 95% confidence interval estimate of the mean VAS score for patients given the sham treatment. You may do the shortcut.
Answer:
(3.442 ; 6.558)
Step-by-step explanation:
Given :
Mean score after patient is given the magnet treatment :
Mean score, xbar = 5
Standard deviation, s = 2.4
Sample size, n = 20
The confidence interval :
Mean ± margin of error
Margin of Error = Tcritical * standard error
The critical value at 95%, df = 20 - 1 = 19
Tcritical = 2.093 (T-student distribution)
The standard error = s/√n = 2.4 / √20 = 0.5367
The margin of error = 2.903 * 0.5367 = 1.558
The confidence interval :
Xbar ± Margin of error
5 ± 1.558
(3.442 ; 6.558)
